BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Bronze San Remo Runner’.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum×morifolium ‘San Remo Runner’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within a population of plants of ‘San Remo Runner’ in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in October, 2007.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in February, 2008. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bronze San Remo Runner’. These characteristics in combination distinguish ‘Bronze San Remo Runner’ as a new and distinct Chrysanthemum plant:

-   -   1. Uniform, upright, outwardly spreading and rounded plant         habit; moderately vigorous growth habit.     -   2. Freely branching habit; dense and full plant habit.     -   3. Freely flowering habit.     -   4. Large decorative-type inflorescences with greyed         orange-colored ray florets.     -   5. Long flowering period.     -   6. Excellent garden performance.

Plants of the new Chrysanthemum differ primarily from the parent, ‘San Remo Runner’, in ray floret color as plants of ‘San Remo Runner’ have dark pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Tardel’, not patented. In side-by-side comparisons conducted in Staden-Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Tardel’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flowered earlier than plants         of ‘Tardel’.     -   2. Plants of the new Chrysanthemum had decorative type         inflorescences whereas plants of ‘Tardel’ had daisy type         inflorescences.     -   3. Plants of the new Chrysanthemum and ‘Tardel’ differed in ray         floret color as plants of ‘Tardel’ had yellow-colored ray         florets.     -   4. Plants of the new Chrysanthemum were not susceptible to Rust         pathogens whereas plants of ‘Tardel’ were susceptible to Rust         pathogens.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum×morifolium ‘Dark San Remo Runner’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons conducted in Staden-Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differ primarily from plants of ‘Dark San Remo Runner’ in ray floret color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Bronze San Remo Runner’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer and autumn in 19-cm containers in an outdoor nursery in Staden-Oostnieuwkerke, Belgium and under conditions and practices which approximate those generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 10° C. to 25° C. and night temperatures ranged from 5° C. to 15° C. Plants were 5.5 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
